Steam backup files download

AFAIK there is no way, free weekend works the same as normal buy works - you just get license removed after some time.

Happy cakeday! No, it isn't possible unless it is the situation you described. Or if you buy the game before it's release and you can preload then.

In the case you want to do this because you're planning to buy a game and want to play with your friends immediatly after you do - you can ask one of your friends to give you their backup of the game(In steam client,top left menu: Steam->Backup and restore games); When you purchase it,you can restore it from his backup file and you'll most likely have your download size drastically reduced.

Oh,and happy cake day :)

Thanks guys. Unfortunately i don't know anyone who can physically give me the backup and the upload rates here are too slow to let someone send it to me.

Just out of curiosity, in general, is it legal to share the backups you make with the client? For example, can you maintain a website dedicated to the sharing of steam games backups?
